Definitions

  • the present invention relates to oral compositions based on S-adenosylmethionine, or salts thereof, particularly designed for systemic buccal delivery.
  • SAMe sulpho-adenosyl-L-methionine
  • the active principle is normally administered per os (both in liquid or solid form) for example by capsules, tablets etc.
  • D1 discloses a masticable tablet, or sublingual tablet, for an oral administration comprising as active principle SAMe, to be used in the fields of psychiatric manifestations of depressive and neurological type.
  • US 2007/0160660 describes formulations for oral use comprising SAMe and a high quantity of inositole in order to make the product more stable in respect of temperature and humidity (which are two adverse factors) but such high quantity implies rather large dimension of the tablet and therefore the above said swallowing difficulties.
  • US 6,759,359 deals with the same problem as the above said EP 136 464 and suggests gastro-resistant soft-gelatin capsules in order to allow a duodenal adsorption, also in this case the same drawbacks (long time of adsorption) are present.
  • Formulations for systemic buccal delivery comprising as active principle sulpho-adenosyl-L-methionine are described, in the form of chewing gums, capable of allowing the absorption of said active principle through the oral mucosa.
  • SAMe sulpho-adenosyl-L-methionine
  • Medicated chewing gums are described in Eur. Ph. 6.0 as "single-dose preparations with a base consisting mainly of gum that are intended to be chewed but not swallowed".
  • European Pharmacopoeia also states that chewing gums contain one or more active substances which are released by chewing. After dissolution or dispersion of the active substances in saliva, chewing gums are intended to be used for systemic delivery after absorption through the buccal mucosa or from the gastrointestinal tract.
  • composition of medicated chewing gums includes, apart from active(s) ingredient, gum base, bulk sweeteners, flavours, softeners, etc.
  • the main components of the gum base are elastomers (polyisobutylene, butyl rubber, etc.), plasticizers (resins, polyvinyl acetate, etc.), texturizers (fats, microwaxes, lipophilic emulsifiers, etc.), and fillers (calcium carbonate, talc, etc.).
  • the first one is the "conventional melting method” that involves various steps, briefly: melting of the gum base, addition and blending of the other ingredients, kneading and rolling of the mixture, cutting and seasoning of the gums. If necessary the process can include a final coating.
  • the "cooling and grinding method” requires the refrigeration of the gum composition until it becomes sufficiently brittle to make possible the grinding. This method requires special equipment and a careful control of the humidity during the process and, moreover, can be potentially hazardous if liquid nitrogen is used as cooling agent.
  • the manufacturing method uses the directly compressible gum bases commonly available on the market (direct compression method) for example: “Pharmagum ® ", developed by SPI Pharma, "All In Gum” by Cafosa, or “MedGumBaseTM” by Gum Base Co just to quote some.
  • the manufacturing process is faster using the above said method and this allows to overcome the drawbacks of the other methods.
  • the gummy matrix of chewing gums assures a good protection against the humidity as shown in Table 1 below, and permits to maintain the KF value (moisture determined in according to Karl Fisher method) well below the 2% limit, that those skilled in the art known to be the maximum allowed to have a good stability of the product.
  • formulations according to the invention allow a protection of the active principle against light, and oxygen effects.
  • chewing gums can be coated with a coating layer that has several functions. The first one is to give an immediate and strong taste sensation when the patient starts chewing. The coating can also protect the gum base, and other ingredients in the core, from the oxidation and makes possible to prolong the shelf-life. Chewing gums can be coated with a sugar-coating, or with a sugarless coating, or with a film coating.
  • the coating layer not only acts as a taste enhancer but can also contain active ingredients.
  • active ingredients contained in the coating layer are vitamins, mineral salts, oligoelements, aminoacids, and mixtures thereof of the kind normally used for this kind of formulations.
  • the coating layer consists mainly of sweeteners and flavours, possible sweeteners are sugarless sweeteners as xylitol, sorbitol, maltitol, isomalt, and the like. Often the low sweet sensation due to the sugarless sweeteners is increased using a high-intensity sweeteners as acesulfame K, acesulfame salts, aspartame, cyclamate and its salts, saccharin and its salts, glycyrrhizin, thaumatin, and the like.
  • the coating layer can also contains other ingredients such as dispersing agents, as well as colouring agents, film formers, and binding agents.
  • the coating layer may be applied in a coating pan or in a fluid bed equipment.
  • the coating layer is applied by double-press coating, also known as compression-coating. This technique does not require water or other solvents during the application making it more advantageous in comparison with the film coating or the sugar coating procedure above all when hygroscopic active ingredients are used.
  • the manufacturing process is carried out with special rotary tabletting machines that automatically perform following steps: load of the bottom layer of the coating into the die from the hopper, centering of the core on the bottom bed of coating, deposition of the top layer of the coating, compression of the whole system by passing the punches between the compression rolls.
  • the composition can be completed with acceptable excipients, such as diluents, binders, lubricants, glidants, disintegrants, surfactants, colorants, and mixtures thereof.
  • acceptable excipients such as diluents, binders, lubricants, glidants, disintegrants, surfactants, colorants, and mixtures thereof.
  • the particular excipient used depends on the means and the purpose for which the active ingredient is applied.
  • Preferred diluents are mannitol, sorbitol, xylitol, microcrystalline cellulose, silicified microcrystalline cellulose (e.g., Prosolv ® available from JRS Pharma) cellulosic polymers, such as hydroxypropylmethylcellulose and hydroxypropylcellulose.
  • glidants include, but are not limited to, silicon dioxide, colloidal silicon dioxide, calcium silicate, magnesium silicate, talc, and mixtures thereof.
  • a binder can be added.
  • Suitable binders include, but are not limited to, methylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose, polyvinylpirrolidone, gelatin, polyethylene glycols, starch and starch derivatives, sugars, glucose, sorbitol, natural and synthetic gums (e.g., acacia, alginates, carrageenan, xanthan gum, arabic gum), waxes, combinations thereof, and any other binder substances known to those of skill in the art.
  • a lubricant can be used.
  • Suitable lubricants include, but are not limited to, calcium stearate, magnesium stearate, glyceryl monostearate, glyceryl behenate, glyceryl palmitostearate, hydrogenated vegetable oil, mineral oil, sodium stearyl fumarate, stearic acid, combinations thereof.
  • disintegrants can also be added to the composition to break up the dosage form.
  • suitable disintegrants include, but are not limited to, starch and starch derivatives, sodium starch glycolate, croscarmellose sodium, crospovidone, alginic acid, microcrystalline cellulose, lower-substituted hydroxypropylcellulose, sodium alginate, and combinations thereof.
  • the formulations can contain a sweetener or a high-intensity sweetener to impart a pleasant flavor to the composition.
  • suitable sweeteners for use in the present invention include natural sweeteners such as sucrose, dextrose, fructose, invert sugar, mannitol, sorbitol, thaumatin, and the like, as well as synthetic sweeteners such as saccharin, aspartame, acesulfame K, cyclamates, sucralose, and other commercial artificial sweeteners well-known to those of skill in the art.
  • the sweetener is added in the amount sufficient to achieve a desired sweetness. Typically, the sweetener is present in an amount from about 0,01% to about 5%.
  • the quantity of active principle is normally comprised between 50 and 1000 mg, preferably is comprised between 100 and 800 mg, and more preferably is comprised between 200 and 400 mg.
  • nutraceutically active agents can include, for example, dietary supplements, minerals, vitamins, and the like, and combinations thereof.
  • nutraceutically active agents include, e.g., vitamin A, vitamin D, vitamin E, vitamin B1 and derivatives thereof, vitamin B2 and derivatives thereof, vitamin B6 and derivatives thereof, vitamin C and derivatives thereof, vitamin B12 and derivatives thereof, folic acid and folates, acetyl-L-carnitine, Co-enzyme Q10, calcium, magnesium, iron, selenium, chromium, zinc, proteins, amino acids, alpha-lipoic acid, silymarin, oligosaccharides, and the like, and mixuters thereof.
  • pH-modifying agents can be added; said pH modifying agents are for example chosen among amino acids (as for examples L-Lysine or L-arginine), carbonates or a bicarbonate, a phosphate or a citrate salt of the kind normally used for oral formulations.
  • the chewing gums, according to the invention can be easily prepared according to the techniques and methods known in the art for this kind of products.
  • the SAMe as well as the other active ingredients if present, is mixed with the directly compressible excipients together with the other appropriate excipients (e.g., binders, glidants, disintegrants, lubricants, sweeteners, flavours, colourants, etc.) for a sufficient time to reach the uniformity of distribution. Then the mixture is loaded to a tabletting machine and compressed following standard procedures.
  • the directly compressible excipients e.g., binders, glidants, disintegrants, lubricants, sweeteners, flavours, colourants, etc.
  • the preferred method is the dry granulation that can be performed both in a tabletting machine and in a roller compactor.
  • the gum base (All-In-Gum SF) is loaded in a suitable blender and the lumps, if present, are broken. In the same blender, SAMe tosylate, L-arginine, aspartame, mint flavour powder, and Talin are incorporated. Following, the mint liquid flavour and the Sipernat 50S are distributed homogeneously. Finally, the magnesium stearate is added to the blender and mixed for 1 minute.
  • Tablets are prepared with an individual weight of 2800 mg.
  • Chewing gums prepared as described in Example 1 are loaded in a coating pan and sprayed on with a suspension composed by: Hypromellose % 46,0 Macrogol 6000 % 16,0 Titanium dioxide % 15,0 Talc % 15,0 Saccharin sodium % 6,0 Mint Flavour % 2,0
  • the coating suspension is applied by means of an automatic spray system until a weight gain of about 200 mg/tablet is reached.
  • the gum base (MedGumBase) is loaded in a suitable blender and the lumps, if present, are broken.
  • SAMe SD4, sodium bicarbonate, talc, mint flavour powder, and Talin are incorporated.
  • a pre-mixture of folic acid and vitamin B 12 carefully distributed into the Maltisorb is added and mixed.
  • magnesium stearate and Compritol 888 are added to the blender and mixed for 1 minute.
